Have you tried using just the new (replacement) 512Mb RAM module in slot 1, without the 256Mb original module installed? It sounds suspiciously like the original module might be faulty.

What motherboard is in your system please?
Also, are all these RAM modules you mention cheap, generic ones or are they quality brands such as Kingston, Kingmax, Geil, Corsair or OCZ?
I'm suspecting generic RAM which is having 'issues' with your particular motherboard, and suffering from the fact that Windows XP is rather intolerant of such 'issues'.
My suggestion would be to Use the 512Mb module in Slot 1, wipe the hard drive clean and install Windows fresh and clean, then see if it's stable. If so, add the other module and see if it continues to be stable.

Download and run CPU-Z
Then let us know what is reported as your motherboard make and model, and also what is reported as the make and model of your RAM modules. (You'll need to use the drop-down box on the Memory tab to find info about both RAM modules.
If that is a Gateway PC, it would also help if you let us know what model of PC it is. It's a Gateway what?

I'd also be checking that all fans in the PC are working correctly. It could be an overheating problem.
Also, the info about the display driver problem could have relevence. Perhaps the display driver is corrupted. Try this:
* download a display driver installation package from www.nvidia.com I'd suggest you use the 'Archived drivers' there, and download the last of the 4x.xx series drivers. Later driver versions are not really optimal for GeForce 4 cards.
* Right-click My Computer and choose 'Properties' to bring up System Properties. Run Device Manager from the Hardware tab. Locate the entry for the display card and choose Uninstall. Do not reboot.
* Use Add/Remove programs to uninstall any NVidia display driver entries you see there.
* Reboot, and cancel out of any 'Found hardware' dialogues which appear when windows restarts.
* Install the device driver by running the executable file you download from NVidia.
See if that helps.

It may and it may not. I would also reinstall the motherboard chipset drivers, preferably before trying to correct any possible problems with the display drivers.
It might be that your display card is on the blink. Does the fan on it work properly? Is it spinning, and are there any slowdown/speedup fluctuations noticeable when you look at the display card fan running?

Doing the above will possibly fix a software fault with your Graphics driver. If you Graphics card is busted then it won't help and nothing will help except replacing a faulty component, (like a fan for example) or replacing the card if its more serious.
You should do everything to check out the software fault before you spend some cash. Try what Catweazle suggested, but after that, and you have no improvement, if your happy to open up the case on your system, then you could check that the fan is correctly working on the card, it should spin like mad, and appear fairly stable from vibrations. Obviously running an open PC with power on is not ideal, and its up to you if you feel comfortable doing so. With the power off, check that it is clean inside, and the connections are clean.

Hang on, is the monitor connected to the NVidia card? If so, the system shouldn't be running on an Intel Graphics driver. Is there an Intel display entry showing up in Device Manager? I'm curious about what you mean by
but it still is on the Graphics Controller and in system it says Video Controller (VGA Compatible) under other devices..it has a exclamation mark on it.
Please slow down a bit and decribe EXACTLY how you have things connected up there.

Then uninstall that Intel entry (and any Add/Remove programs entry which is related). follow the instructions I gave for uninstalling the NVidia display earlier. Shut down when both parts of the job are complete.
Then power up and go into BIOS setup. See if you can find an entry in there somewhere for the onboard graphics, and disable it if you find one. Save and reboot. Again, make sure you Cancel out of any Found Hardware or Install Device dialogues you might be presented with.
You gotta get rid of that Intel graphics entry for sure.
It might be that a jumper needs to be changed on the motherboard to disable the onboard display. I can't be sure and you might need to contact Gateway's support section to get instructions.
You never did let us know precisely what model that Gateway system is. We might be able to find more detailed info on Gateway's website if we know exactly what we're looking for! ;)

You could try looking at the thing to see if anything is printed on the case, on the label at the back, or in the manual or other documentation which came with it!
